防止しなければならない。The size of a miniaturized surface mount type crystal resonator is about 3.2 mm in the longitudinal direction and about 2.5 mm in the width direction. Since the crystal blank 1 is even smaller, the influence of the support on the electrical characteristics is large, and the fixed part must be produced constantly. Therefore, the application amount of the conductive adhesive must be accurately controlled. Further, since the space between adjacent electrodes becomes narrow, a high-viscosity adhesive (for example, 1
2000 CPS) to prevent short circuits due to adhesive flow.

ディスペンサーの吐出量が変化してしまう。The viscosity of a high-viscosity material (generally 10000 CPS or more) greatly changes in viscosity depending on the environment, and in particular, greatly changes in viscosity due to temperature. Therefore, when the temperature environment changes, the discharge amount of the dispenser changes.
